BD6212FP-EVAL-N: DC Brush Motor, 3 ~ 5.5V

This evaluation board has been developed for ROHM’s H-Bridge driver customers evaluating the BD62x2FP series. The BD62x2FP series can operate across a wide range of power supply voltages (from 3V to 32V max), supporting output currents of up to 2A. PWM signal control (20 kHz-100 kHz) or VREF control modes are used to vary motor rotation speeds.

ROHM’s ICs are complete with over current protection (OCP), over voltage protection (OVP), thermal shutdown (TSD) and under voltage lock out (UVLO) protection circuits while also facilitating a low-power consumption design (10μA max). Overlap (shoot-through) protection to prevent high currents during motor reversal or breaking is also built in. In addition, the devices are designed to withstand up to 4 kV ESD.
